Hello all,

Do i get any info any or links to buck and boost power dc/dc converters ?

Sully
 

whata coincidence!
try this link.
also with really simple
program for calcs,so easy!!!!!!!
so good a chip LM2576

For the basic principle read ArtOfElectronics. You can build a switcher yourself with PWM output of a PIC for example. But make sure your PIC never crashes :smile:

For good efficiency yet simple to use circuits look up Nationals SIMPLE SWITCHER series.
 

Buck -> Step-down converter
Boost -> Step-up converter

Buck : mainly PWM control
Boost : PWM,PFM.VFM control

Operation Mode : Continuos / Discontinuos Current Mode( according to inductor current)

Basic Topology -> TEXT BOOK ...

Thanks.

who can send me some MCU control DC-DC sch
 

hi all.
I want to know theoretical and practical m@x response frequency of dc/dc converters, and which componets make the m@x response frequency limits?
thanks.
 

you can use the mentor analog designer to sim
you design.use it,you can find frequency response.

Re: Buck and boost

It is basic topology for dc-dc,i think you use google,you will find several huandreds imformation about it.

Ti,Maxim,Fairchild,national,All have applications about it.
 

Buck and boost

read the book "power electronics handbook"
upload already.
 

Buck and boost

Basic book:

Power Electronics: Erickson.

See site from Power Electronics Colorado Center.
 

Re: Buck and boost

In these days I am studying the documentation in reference to the argument. I pass to you what I have found!

Hi

Re: Buck and boost

Is there any design/chip capable of auto-switching from step-up to step down (&vice versa) by detecting the voltage output ?

P.S. I don't want to have inverted output => CUK converter is not preferred.

Any idea?
 

Re: Buck and boost

HI,
If you want to spend little motorola proposes with a MC34063 a good application step-up/down that it works!

Re: Buck and boost

SEPIC converters will do either Buck or Boost without inversion.

Linear Technology, LTC3441 can do that function
